Prevention of fungi and molds in poultry and animal feedstuffs with methyl rosaniline chloride additive

Abstract

An animal or poultry feed additive which is effective for inhibiting or preventing microbial activity, fungi and mold growth in feeds to which it is added provided by dispersing methylrosaniline chloride on an acid-treated mineral carrier.

I claim: 
     
       1. A poultry or animal feed product protected against microbial activity, fungi and mold growths, comprising a basal feed ration containing ground feed materials in intimate admixture with a substantially dry, finely-divided, non-toxic, mineral carrier having from about 0.05% to 5.0% by weight of methylrosaniline chloride dispersed thereon, said mineral carrier having incorporated therein by adsorption or reaction from about 0.1% to 10% by weight of a non-toxic acid based on the weight of the carrier, said acid being one which is adsorbed by or forms water soluble reaction products with said carrier, to thereby facilitate the release of said methylrosaniline chloride from the carrier in the presence of moisture. 
     
     
       2. The feed product of claim 1 wherein the acid-treated carrier contains from about 0.1 to 5% by weight, based on the weight of the carrier, of methylrosaniline chloride, and said acid-treated mineral carrier is present in the feed product in an amount of from about 0.1 to 25 pounds per ton of feed. 
     
     
       3. The feed product of claim 1 wherein the mineral carrier is a poultry feed supplement which has been treated with acetic acid. 
     
     
       4. The feed product of claim 1 wherein the mineral carrier is calcium carbonate which has been treated with acetic acid. 
     
     
       5. The feed product of claim 1 wherein the mineral carrier is selected from the group consisting of ground limestone, dolomite, defluorinated rock phosphate, tricalcium phosphate, dicalcium phosphate and calcium carbonate.
